SHIELD FOR FUR'NACES, 80C.

SPECIFICATION forming part of Letters Patent No. 242,250, dated May 81,1881.

Application tiled September 27, 1880.

To all whom it may concern Be it known that I, JOHN G. BATTELLE, ofMemphis, in the county of Shelby and State of Tennessee,have invented acertain new and useful Improvementin Shields forFnrnaces andFurnace-Doors; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had totheaccompanying drawings, and to the letters of io reference markedthereon.

My invention relates to an improvement in shields for furnaces andfurnace-doors; and it consists of a furnace-door having a shieldattached thereto with air-circulating space between the latter andformer.

Y My invention also consists of a furnace-door having a shield attachedthereto, with an airspace between the latter and former, in combinationwith a shield or casing for the furn ace 2o wall or walls, as willhereinafter more fully appear.

To enable others skilled in the art with which myinvention is mostnearly connected to make and use it, I will proceed to describeits con-2 5 struction and operation.

In the accompanying drawings, which form part of my specification,Figure lisa side elevation of an ordinary heating or puddling furnacefurnished with my improvement. Fig.2

3o is a vertical section of the same at line x of Fig. l. Fig. 3 is avertical section of the saine at line y y of Fig. l.

In the accompanying' drawings, Arepresents the furnace, in front of theworking side of which is placed a shield, B, of any of the known forms,and may be constructed of iron or oak wood, or by the combination ofcottonseed hulls and a case of sheet metal, or said -hulls inelosedbetween walls of sheet metal, 4o said shield being so arranged withrelation to the wall that an air-space will be between said shield andthe furnace-wall for the free passage of air. The means for supportingthe shield and holding itin a fixed or movable po- (No model.)

sition with relation to the furnace-wall I leave 4 5 to the judgment andskill of the mechanic.

The door O of the furnaceis of the ordinary construction. To the frontwall of the dooris attached by means of the arms D a shield, e, whichconsists of a case, of sheet metal filled with cotton-seed hulls; lontsaid shield e may be made of iron, oak wood, or other material. Theshield e moves with the door in the manipulating of it.

The advantage of a shield in combination with the furnace will beapparent when the fact is taken inte consideration that the face of theoperator is, from necessity in working heating and puddling furnaces, inthe manufacture of iron and steel, brought in close proX imity with thefurnace-door, and the heat reiiected or radiated therefrom produces onhim a very debilitating effect. The shield e, combined with the door,will to a very great de. gree relieve him from this heat and itsdepressing iniiuenee, and when said shield and door is combined with theordinary furnaceshield the operator is almost entirely freed from thereliected or radiated heat of the furnace, which is a greatconsidera-tion in warm weather.

Having thus described my improvement, what I claim isl. A furnace-doorhaving a shield attached thereto, with an air-circulating space betweenthe latter and former, substantially as herein described, and for thepurpose set forth.

2. A furnace-door having a shield attached thereto, with an air-spacebetween the latter and former, in combination with a shield or casingfor the furnace wall or walls, substantially as herein described, andfor the purpose set forth.
